Educational Strategies for Teaching Metabolic Profiles Across Three Endurance Training Zones.

This article explores an innovative educational approach using a metabolic board designed to enhance understanding of muscle metabolism across three endurance training zones: Z1 (light intensity), Z2 (moderate intensity), and Z3 (intense/severe intensity). The aerobic threshold marks the transition from light to moderate domains, and the anaerobic threshold separates moderate from intense domains, with both thresholds adapting to training. Exercises within each training zone elicit specific adaptive responses through distinct signaling pathways, but the metabolic profile induced remains relatively constant across these intensity domains. The assembly of the metabolic board is guided by interpretative questions derived from recent incremental exercise studies. By interacting with the board, students gain clear insights into the rationale for choosing between continuous and interval exercises. This interactive tool simplifies complex physiological processes into understandable components, clarifying the relationships among motor unit types and its metabolism and principal energy sources at each intensity level. By assembling the board, students demystify muscle metabolism as a continuum of responses crucial for sustaining various exercise intensities. This integration of theoretical knowledge with practical application empowers students and professionals to make informed decisions about training prescriptions, a critical element of training periodization.
